SNAP-Hook.

Specification of Letters Patent.

Application tiled May 31, 1911.

Serial No. 630,467.

Toall ywhom it may concern.'

Be 1t known that I, YALTER. R. Ynaonn, a citizen of the United States,res1dmg at.

Eddington,` in the county of'vBueks,-Stat'e of.

Pennsylvania, have invented a newand useful Snap-Hook, of which the following is a specification.

. My invention consists ofv a snap hook having a hook proper, a tongue adapted to close said hook proper. and a member adapted to engage said tongue and hold it positivel \7 in closed position.

It consists also of ydetails of cmistruction represents a transverse section on line ,2-2

Fig. 2. Figs. and 7 representI side elevations of other embodiments ot my inven tion. Fig. S represents alongitudinal section of Fig. 7. Fig. t) renesents a perspective view-of a portion of Fig. 7 detached. Fig. 1() represents a section on line a-d Fig. 7 on an enlarged scale.

Similar letters of reference indicate corresponding parts in the` figures.

Referring to the drawings z-A designates the hook proper of the device and l the closing tongue thereof, vsaid tongue being mounted on the ears C which latter are connected f with the shank D from which said hook A extends.4 In the cross bar E whichconnects the cars is an opening which is occupied by the rod F, which is slidable in the longitudinal direction of the shank D and has secured to it on the end toward the'hook A the block (hand on the other end the knob or head H, it being noticed that said ears (l extend upwardlyfrom the top' of saidcross bar, which latter is raised from the shank D, forming onthe side away from the hook the recess J which contains the spring K, which encircles the Patented May 7, 1912.

poitionjof the rod F which passes throughf said recess and bears against the cross bar E and the head H, so as to hold theblock G 1n closing ory normal position, as ,will be hereinafter again referred to.

` On. the inner or under side of the tongue B is the lug L, the same having an oblique (ii-slantng side LNI, Whichlatter faces the slant'ing side N, thesame facing t-he ear C, which sides M N are adapted to come in Contact, as will be hereinafter again referred to. It will be noticed that in the normal or closed position of the tongue B, the block hook A. The block G has anoblique or.-

G, contacts with the lug L and a's said block 70 is subject to the pressure of the spring J and the lug rests on said block, it is evident that the tongue will. be held against the nose of the hook A and so be closed tight-ly and positively. When thetongue is to be released, the head H is' pushed in when the block G is removed from beneath or behind thelug L, and as the latter is no longer suppmted, the tongue then dropping, and the snap hoo-k as such `is opened for lpurposes redini-mg the same. When the head H 1s let go, the spring J restores the block G tol its normal position, its oblique faceN riding on the oblique face M of the lug and so'pressing the latter as to ralse ormove the tongue toward the nose of the hook A.

As the block continues its return motion, its

outer edge, in the present instance, its up er edge passes under the outer or lower e geA ot' the lug L and so moves the lug and consequently ther tongue B to full Closin the block G, and sois renderedposit-ively ex; tent., the. tongue being supported agalnon immovable untilthe advance operation of.' `7` the head H is repeated.

It will benoticed that the the head H are sustained .on the shank-D in 'block G andall of their positions, vthus rendering the device in those respects compact and ir'm.'

The head H is adapted to enter the recess J and so is 'guided therein true in its motions,l

while being movable ont-he shank D as has.

been state( It is'to lie noted that the-recess .I Which.

lis 'in' the base ofthe ears C 'is entirely inelosed so as to lprevent ingress of yforeign smgle ended with an eye oigringP on the about the pintle R of said tongue while also freely inclosing said ears, the end portionsl of said pintle passing through said sheath withoutwhowever affecting the movements of the tongue inv opening and closing, it being noticed thatsaid sheath protects the axial portion of the tongue and particularly the` space existing between the ears C from the entrance of dust, dirt and foreign matters generally.

In some cases, it may be desirable to prevent the dropping or opening movement of "the tongue when the block Gr is removed from the lug L. For this purpose, there is secured to the pintle R, the spring S which bears upwardly and outwardly against the underside ofthe said tongue so as to hold thelatter in closed position,'it being evident by pressing said tongue toward the shank the spring will be overcome and so the tongue-will leave its seat on the hook and assume an open position for' purposes requiring the same.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

In a snap hook, a hook proper and a shank carrying the same, a pivoted tongue with a lug extending inwardly therefrom and having an oblique surface on the side facing 40 saidhook proper, a pair ofvears on said shank on which said tongue is mounted, a cros's'bar joining said ears forming a recess opening away from said hook proper, there being an opening in the wall of the cross bar from said recess toward the hook proper, a rod slidably mounted in said opening, a head on one end of said rod and movable in said recess, a spring contained in said recess, and a block on the other end of said rod and having an oblique surface on the side facing the -cross bar, the action of the spring upon the head forcing the block to- Ward the cross bar and beneath said lug to lock the tongue in closed position.
